CAR-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 377,770, dated February14-, 1888.

Application filed December 17, 1887. Serial No. 258,229. (No model.)

' To all whom it may'concern:

Be it known that I, Gnonen DEoARIE PEAR- SON, a subject of the Queen ofGreat Britain, and a resident of the city of Montreal, in the Districtof Montreal and Province of Quebec,

Canada, have invented new and useful Improvements in Oar-Couplers; and Ido hereby declare that the following is a full, clear, andv exactdescription of the same. to The present invention has reference tofurther improvements in my previous invention in car-couplers for whichLetters Patent of the United States were granted on the th day ofDecember, A. D. 1885, No. 332,430, to so ar- 'r 5 range the couplertherein set forth that an ordinary link and pins may be used in combination therewith for further securing the cars together, and suchimprovements as may be hereinafter set forth.

The particular combinations of parts which form my present inventionwill be hereinafter set forth and claimed. 7 A

In the drawings hereunto annexed similar letters of reference indicatelike parts, and

2 these will also be made, as far as convenient, to agree with theletters of reference used in the specification ofthehereinbefore-mentioned' patent. v

Figure 1 is a side elevation embodying my present invention. Fig. 2 is aplan of the invention shown in Fig. 1. Fig. 3 is a vertical sectiontaken on line m m, Fig. 2. Fig. 4is a modification of my invention shownin section, also as taken at line :0, Fig. 2. Fig. 5 is an.

5 illustration of how one of my improved couplers may be used inconnection with many of the forms of hunters at present in use. Fig. 6is a detail of construction.

Letter A is a portion of the body of a car,

B the end of frame, 0 the dead-head, and D the strap or gland, allarranged as described in my said former patent.

In this specification the back of the hunter is the end whichextendsunder the car. Therefore, when any part or thing is spoken of asbeing at the back of another, it will be understood that it isrelatively so placed. The front of the hunter is the extreme end of thehunter which projects out beyond the car, and when any part or thing isspoken of as being in front of any other part or thing it will beunderstood to be relatively so placed.

E are the bodies of the bunters, (sliding in the straps D,) provided attheir front ends with extensions F, as shown in Figs. 1 and 2, havingopen spaces G and H, pivot bolts or pins K, and pawls L, constructed andarranged as in my said previously-patented invention, excepting thefollowing changes, hereinafter mentioned:

Instead of the pins I. described in my said previous patent, I in mypresent invention form bridge-pieces I, integral with the ends of theextensions F, upon which the pawls L hook in a similar manner that theyare described to hook on the pins I in my said previously-patentedinvention when both said pins I are in place.

In this present invention I extend the extensions F downward (see Figs.1, 3, and 4.) an amount required for forming a suitable space,

. M, for a link, N, and asecond bridge-piece, I.

In the modification shown in Fig. 4 three bridgepieces, I, are provided,forming two spaces, M, for the link N to be placed in, and

thus, if the cars are of very unequal heights, provide for the same.Through the bridgepieces I holes 0 areformed for the reception.

of pins P, and, furthermore, in the top bridgepiece I a counterbore, R,is provided of suitable size for the heads of the pins P to be receivedin, (see Figs. 3 and 4,) so that the said heads may not form anyobstruction to either of the pawls L coming to the position shown at 3,Fig. 3.

In my present invention eyes may be formed on the upper sides of thepawls L for lifting them by, as shown and described in my said buntersof two cars can be brought together, after which the link may beintroduced from the back of the space M, as shown by the position of thelink 1, and placed in the position 2, (see Fig. 5,) the position 2 beingalso the position the link is shown in in Figs. 2 and 3. By thisarrangement the cars may be coupled with an ordinary link and pins, thenovelty in this case consisting in the particular arrangement of theparts by which (the ends of two hunters of two cars being broughttogether, and while the cars are stationary in such said position) thelink N may be placed in position from the back of the space M, afterwhich the pins P may he put in place. The abor e also enables one of myimproved bunters to be engaged in a similar manner with many of theordinary forms of hunters at present in use, as illustrated in Fig. 5,where A may be taken to be one of the ordinary forms of hunters, and Pthe ordinary pin therefor.

When it is desired to use the link N in combination with the pawls L forholding the cars together, the pawls L will be provided, their back endsbeing pivoted in the spaces H by the pivot-bolts K. After the ears havebeen brought together and the pawls L have assumed theposition shown inFig. 3, or by dotted lines in Fig. 1, (the cars being station ary,) thepawls may he raised to a vertical position, as shown in Figs. 1 and 2,when the link N and pins P may be put in place, after which the pawlsmay be returned to the position shown in Fig. 8.

If the link N is made with extra length beyond the length that isrequired for putting the pins P P in place, as shown in Figs. 2 and 3,the link will only come into action in holding the cars together afterthe pawls have given out, or are not employed for holding the carstogether, in which case the link N forms only a second coupling in caseof any derangement of thesaid pawls L; but if the linksN are made acorresponding fit or length to the pins P that the pawls L are to thebridge-pieces I, the strain to draw the cars apart will be jointly borneby the one pawl L and link N in combination.

WhatI claim, and wish to secure by Letters Patent, is as follows:

1. As an improved article of manufacture or construction, a hunter-bodyhaving extensions and bridge-pieces, as described, said bridgepiecesbeing provided with holes for the introduction of the coupling-pin, andwith a space between them for the coupling-link, said space for the linkbeing situated (as shown and described) in relation to the body of thehunter so that the link may be placed therein from the back thereof, thewhole substantially as described and shown.

2. As an improved article of manufacture or construction, a hunterhaving extensions and bridge-pieces, said bridge-pieces being providedwith holes and couuterbore for the reception of the coupling-pin andhead thereof, and also provided with a space between them for thereception of the coupling-link, the said space for the link beingrelatively so situated (as shown and described) that the said link canbe placed therein from the back thereof; furthermore, the said hunterbeing provided with a recess or opening, H, and pivot K, passing throughthe one end of the pawl and attaching the pawl thereby, and with said.pawl, the whole substantially as described and shown.

3. The combination, in car-couplings, of a hunter body, E, havingextensions F, and bridge-pieces I, provided wit-l1 holes 0, and havingspace M, situated (as described and shown) relatively so that the link Nmay be placed therein from the back thereof, the said hunter having thesaid parts, with another hunter similarly constructed, and with pins Pand link N, the whole substantially as described aud shown.

4. The combination, in carcouplings, of the hunter-body E, extensions F,and bridgepieces I, arranged to form the spaces G, H,and M, and thebridge-pieces I being furthermore provided with the holes 0 andcouuterbore R, the said space M being relatively so situated to the bodyof the hunter that the link N may be passed and placed therein from thehack thereof, pawl L, pivot-boltK,by which the said pawl is attached andpivoted in the space H, one hunter having the said parts with anotherhunter similarly constructed, and with coup ling-pins P P and link N,the whole substantially as described and shown.
